Step 12 - Review the Calibration Results

1. When the calibration of the ACR3 Probe Changer is complete, select the Ports tab in the Probe Changer dialog box (Edit | Preferences | Probe Changer). This tab displays the calibration information for the location of each calibrated port. For example:

Probe Changer dialog box - Ports tab with calibration results

2. When you view the results, look for the following. Any significant deviations from these expectations may be due to a bad hit.

- This rack MUST BE aligned parallel to either the X or Y axis of the CMM. This means that in one of these axes, there should be little or no change between ports.

- In the other (X/Y) axis, you should see only the distance between the ports (roughly 35 mm).

- The Z values should be nearly identical, since the ports are all at the same height.

The results during measurement routine execution are:

1. During measurement routine execution, probe entities that are added to each port are automatically picked up from that location whenever PC-DMIS executes a LOADPROBE command for that probe.

2. The probe body moves to the mount point and then into the port to drop off the current probe, which pushes the lid backwards.

3. The machine DCC movement slides the rack from the right to the left side of travel, turning the key in the process to unlock the probe from the wrist.

4. The probe then moves out from the port and into a different port to load the next probe. At this point, the DCC movement slides from the left to the right to lock this probe onto the wrist.

5. Finally, the probe travels out of the port and to the rack’s mount point.

6. From there, it continues to measure.
